3d0a45f6e5 scheduler: Add is_set/is_not_set constraints
This adds constraints for asserting that a given attribute or value
exists, or does not exist. This acts as a companion to =, or !=
operators, e.g:

```hcl
constraint {
        attribute = "${attrs.type}"
        operator  = "!="
        value     = "database"
}

constraint {
        attribute = "${attrs.type}"
        operator  = "is_set"
}
```

0925bfe618 scheduler: Allow comparisons of nil values
This commit allows the ConstraintChecker to test values that do not exist.
This is useful when wanting to _exclude_ given nodes from executing a
job, for example, if you wanted to give canary nodes an attribute, and
not run critical services on them, you may specify something like the
below, but not want to tag all other nodes with the inverse.

```hcl
constraint {
  attribute = "${node.attr.canary}
  operator = "!="
  value = "1"
}
```

This also requires all constraint checkers to allow for nil target
values, as they will no longer be short circuited by resolving a target.

9f7dfb17a5 Fix logic bug in tracking sum of matched affinity weights
We need to track the sum of matching weights per device, but only
change the final return value if its the highest scoring choice

66670c0f02 Fixes device scheduling unit tests
Also changes the logic for score when there is more than one task
requesting a device. Since inter task affinities are already normalized,
we take the average of the scores across tasks.

0397cbc8d1 Duplicate blocked evals cancelling improved
The old logic for cancelling duplicate blocked evaluations by job id had
the issue where the newer evaluation could have additional node classes
that it is (in)eligible for that we would not capture. This could make
it such that cluster state could change such that the job would make
progress but no evaluation was unblocked.

715d869499 Implement preemption for system jobs.
This commit implements an allocation selection algorithm for finding
allocations to preempt. It currently special cases network resource asks
from others (cpu/memory/disk/iops).
